Referring to fig. 1-5, in one embodiment, a socket-replaceable cross wrench includes two rod bodies 1 and a plurality of sockets 2, the two rod bodies 1 are fixed together at their middle portions to form a cross shape, an insertion portion 3 with a polygonal cross section is disposed at an end portion of each rod body 1, an insertion hole 7 is disposed at an end of each socket 2 facing the insertion portion 3, a socket hole 8 is disposed at an end of each socket 2 far from the insertion portion 3, the socket hole 7 is adapted to the cross section of the insertion portion 3, and the socket hole 7 is detachably inserted into the insertion portion 3. The rod body 1 may be circular, hexagonal, or quadrangular or 8-deformed, among other shapes. The detachable connection of the connection-peg 7 and the connection-peg 3 can be specifically a snap connection or an interference fit, etc.

Preferably, a counter bore 4 is arranged on one surface of the inserting part 3, a spring 5 is arranged in the counter bore 4, a ball 6 is movably connected in the counter bore 4, one end of the spring 5 is abutted against the bottom of the counter bore 4, the other end of the spring 5 is abutted against the ball 6, the ball 6 is limited in the counter bore 4, and the upper end of the ball 6 protrudes out of the counter bore 4; the upper end of the ball 6 is abutted against the side wall of the inserting hole 7.

Two body of rod 1 have 4 grafting portions 3, and the quantity of sleeve 2 specifically can be 4, also can be 3, certainly can also be 5, 6 etc. when the quantity of sleeve 2 is greater than 4, remaining sleeve can be reserved for use, and the size of sleeve can be different to adapt to different work demands. The cross section of the plug part 3 may be hexagonal, or quadrangular or 8-deformed, etc. The cross section of the plug-in part 3 can also be circular with one flat surface or circular with two flat surfaces, which is also considered to be a polygonal category.

An arc-shaped groove 9 is formed in the side wall of the inserting hole 7 and in the position corresponding to the ball 6, and the ball 6 is clamped with the arc-shaped groove 9. Therefore, the ball 6 is clamped with the arc-shaped groove 9, so that the sleeve 2 is more stably connected with the plug-in part 3.

The plug hole 7 with sleeve hole 8 passes through-hole 10 intercommunication, the aperture of through-hole 10 is less than plug hole 7 and sleeve hole 8's aperture, through-hole 10 orientation the terminal surface of grafting portion 3 one side forms spacing terminal surface 11, the top of grafting portion 3 with spacing terminal surface 11 butt. The through-hole 10 can be used for better processing when the whole sleeve 2 is processed, and can reduce the weight of the sleeve 2 on the basis of not reducing the structural strength and facilitate transportation. The effect of spacing terminal surface 11 can make sleeve 2 more stable with being connected of grafting portion 3, has played the effect of avoiding radial displacement.

The through-hole 10 is circular.

The outer diameter of the insertion part 3 is smaller than that of the rod body 1, a limiting step 12 is formed at the joint of the insertion part 3 and the rod body 1, and the end face of the sleeve 2 is abutted to the limiting step 12. The limiting step 12 also plays a role in enabling the connection between the sleeve 2 and the insertion part 3 to be more stable and avoiding radial displacement. Spacing step 12 and spacing terminal surface 11 two effects are overlapped mutually, further make sleeve 2 and grafting portion 3 be connected stably.

The rod body 1 is provided with a suspension loop 13. The hanging lug 13 can hang the cross wrench when not in use, so that the tool is convenient to store.

The middle parts of the two rod bodies 1 are welded and fixed, and a rubber sleeve 14 is sleeved outside the rod body 1.

The working principle is as follows: the sleeve 2 is spliced and fixed on the rod body 1 through the splicing part 3 and the rod body 1, so that the sleeve 2 is convenient to mount when in use, is convenient to take down when not in use due to the fact that the sleeve is fixed by the butt action of the ball 6, namely, the structure of the application can be used for conveniently replacing different sleeves, can facilitate users to mount the suitable sleeves according to actual requirements, and is more practical. In addition, if one sleeve is damaged, the sleeve can be continuously used only by being replaced, and resources are saved.

The above description is only a preferred and feasible embodiment of the present invention, and therefore, the scope of the present invention should not be limited by the above description, and various other modifications made by the technical solutions and concepts of the present invention should be included in the protection scope of the present invention.
